Windows XP uses the Welcome/Login Screen where the Icons of users in the system are shown with the status of users, But the administrator is not shown by default.

So we have to press Ctrl + Alt + Del and log in using username administrator and correspondent password. This might be not necessary for a user who access admin daily (BOSS). For them we let it show administrator account on the welcome/login screen itself
